01.Maryland has BOTH a state estate tax AND a state inheritance tax.
Maryland is one of only two states with both. State estate tax exemption: $5M per individual (Maryland is unusual in that the exemption hasn't been adjusted in years). State inheritance tax: 10% on transfers to anyone outside the immediate family — siblings, friends, partners, and most beneficiaries other than spouses, children, parents, grandchildren, and siblings of the decedent.
